Abstract (en)

[origin: WO2004019545A1] A modulator (102) modulates a plurality of symbols to create a modulated signal. A transmitter is coupled to the modulator (102). The transmitter transmits the modulated signal if the modulated signal is above a threshold. A minima enlarger (104) is coupled to the modulator (102). The minima enlarger (104) computes an adjustment to the plurality of symbols if the modulated signal is below the threshold. A summer (106) is coupled to the modulator (102) and the minima enlarger (104). The summer (106) adds the adjustment to the plurality of symbols if the modulated signal is below the threshold.
